Some tips for a new hairdo?

Ok, so I am wanting to add some changes to my hair. My hair is dark brown and I do not want to dye it. The length of it is almost completely over my . So my thing is that I do not know what would suit my face. I have a big face (sounds weird, but I really do) and my head is pretty big , to be honest. I have hazel eyes that I emphasize with makeup a lot and I have a strong nose. So basically big head with strong facial features. What kind of hairstyle would look good on me? I do not want to cut it way too short, and I've always liked somewhat long hair. Thanks!
